Programming paradigms for dummies: what every programmer should know Peter Van Roy, 2009
We’ll get back to CIDR’19 next week, but chasing the thread starting with the Data Continuum paper led me to this book chapter by Peter Van Roy mapping out the space of programming language designs. (Thanks to TuringTest for posting a reference to it in a HN thread). It was too good not to take a short detour to cover it! If you like the chapter, you’ll probably enjoy the book, ‘Concepts, Techinques, and Models of Computer Programming’ by Van Roy & Hardi on which much of this chapter was based .
This chapter gives an introduction to all the main programming paradigms, their underlying concepts, and the relationships between them… We give a taxonomy of about 30 useful programming paradigms and how they are related.
Programming paradigms are approaches based on a mathematical theory or particular set of principles, each paradigm supporting a set of concepts. Van Roy is a believer in multi-paradigm languages: solving a programming problem requires choosing the right concepts, and many problems require different sets of concepts for different parts. Moreover, many programs have to solve more than one problem! Continue reading
We’ve spent a great deal of time in the last few posts talking about MPLS both with LDP and with static LSP configurations. While these approaches certainly work, they aren’t the only options to use for label distribution and LSP creation. If we take static LSPs off the table (since they’re the equivalent of static routes and not scalable) we really have two main choices for label distribution – LDP and RSVP. LDP is typically considered to be the easiest of the two options but also offers a limited set of functionality. RSVP offers many more features but also requires more configuration. When you’re designing an MPLS network you’ll have to decide which protocol to use based on your requirements. In many cases a network may leverage both in different areas. In this post the aim is just to get RSVP up and running – we’ll dig into the specifics in a later post.
So let’s get right into a simple lab where we leverage RSVP instead of LDP. Like the previous post, we’ll leverage the same lab environment…
Let’s assume as before that the base configuration of the lab includes all the routers interfaces configured, OSPF enabled on all Continue reading

Intel has been on the hunt for a new CEO for more than seven months. Pundits expected the chipmaker to announce a new chief executive before or on its earnings call today.
Baidu, China’s search and ad giant, has aggressively re-focused its business on artificial intelligence and connected vehicles as the U.S.-China trade war heats up and online advertising becomes less profitable.

HTTP is the application protocol that powers the Web. It began life as the so-called HTTP/0.9 protocol in 1991, and by 1999 had evolved to HTTP/1.1, which was standardised within the IETF (Internet Engineering Task Force). HTTP/1.1 was good enough for a long time but the ever changing needs of the Web called for a better suited protocol, and HTTP/2 emerged in 2015. More recently it was announced that the IETF is intending to deliver a new version - HTTP/3. To some people this is a surprise and has caused a bit of confusion. If you don't track IETF work closely it might seem that HTTP/3 has come out of the blue. However, we can trace its origins through a lineage of experiments and evolution of Web protocols; specifically the QUIC transport protocol.
If you're not familiar with QUIC, my colleagues have done a great job of tackling different angles. John's blog describes some of the real-world annoyances of today's HTTP, Alessandro's blog tackles the nitty-gritty transport layer details, and Nick's blog covers how to get hands on with some testing. We've collected these and more at https://cloudflare-quic.com. And if that tickles your fancy, be sure Continue reading
